Abstract (en)
[origin: WO2011104139A1] The invention relates to a method for producing water-absorbing polymer particles, in which an aqueous polymer gel is dried in a circulating air belt dryer on a continuous conveyor belt and the surface of the conveyor belt has a plurality of raised regions or recesses which are suitable for limiting the mobility of the aqueous polymer gel in the transversal direction.
